Question

Covert 1 joule of work into cgs unit

Answer 1

Explanation:

1 joule is 1 newton × 1 metre

1 J = 1N × 1 m

As, 1N = 10^5 dyne (CGS System)

&

1 m = 100 cm

So,

1 J = 10^5 dyne × 100 cm

1 J = 10^7 dyne×cm

Or

1 J = 10^7 ergs

1 Newton

• = 1 kg × 1 m/s²
• = 1000 gm × 100 cm/s²
• = 10⁵ dyne.

1 Joule

• = 1 Newton × 1 m displacement
• = 10⁵ dyne × 100 cm displacement
• = 10⁷ ergs.

1 Joule

• = 10⁷ ergs
